Description

Technical Field

[0001] This invention belongs to the field of electromechanical engineering technology, and in particular relates to a debugging system and debugging method for electromechanical engineering. Background Technology

[0002] Currently, engineering projects, especially cleanroom projects, are characterized by large areas, numerous instruments, valves, and control cabinets, all scattered across various locations. Due to specific process characteristics, the instrument and valve areas must be precisely matched. To ensure project accuracy, each instrument requires at least two people for commissioning: one on-site and one at the control cabinet. They must disconnect and record the data one by one, ensuring each instrument corresponds to its position on the design drawings. The programs and control diagrams are written and designed according to the design drawings. However, the cabling between the control cabinets and instruments is often not laid by professionals, making errors easy to occur. When such problems arise, a cable locator is typically used to search each location. Even if the cable is found, significant deviations in location necessitate modifying the wiring in the control cabinet and revising the drawings. With a large number of such cases, the actual wiring diagram of the control cabinet often differs completely from the design drawings. Often, commissioning personnel or manufacturers cannot promptly modify the drawings, or simply choose not to. For commissioning personnel or suppliers, modifying the program is sufficient. However, this is cumbersome and costly for the owner's maintenance personnel or for future project expansion. In addition, valves are typically tested with three or four signal segments, namely 4mA, 12mA, and 20mA, to observe the actual valve opening and opening feedback at the field. This testing method is also quite wasteful of personnel resources.

[0003] In summary, the existing technology has the following drawbacks: 1) Instrument accuracy can only be tested manually. One instrument requires two people, two instruments require four people. Improving testing efficiency would only require doubling the number of personnel. Three- or four-stage valve testing also requires the cooperation of engineers and workers, resulting in high labor costs during commissioning. 2) Furthermore, the on-site commissioning personnel and the design personnel are usually not the same person. If on-site modifications or statistics are not made promptly, the personnel involved in the commissioning process will eventually forget about the changes. Also, the wiring inside the cabinet differs significantly from the initial design drawings, which is detrimental to later maintenance and project expansion. Summary of the Invention

[0004] The purpose of this invention is to provide a debugging system and method for electromechanical engineering, which can achieve automatic debugging and simultaneous debugging and drawing modification. To achieve the above objective, the following technical solution is adopted:

[0005] A commissioning system for electromechanical engineering, comprising:

[0006] An oscillation generator is used to generate an oscillation signal. During the path confirmation phase, it is set at the pre-installation position of the component to be tested.

[0007] The field transceiver digital-to-analog circuit processing unit 5 is used to receive the oscillation signal emitted by the oscillator and convert it into a signal type. Its output terminal is connected in sequence to the IO module connector docking unit 1 and the control unit 8.

[0008] The controller unit 8 includes a digital-to-analog circuit processing unit 3 and a signal oscillation generator unit 2;

[0009] The analog-to-digital circuit processing unit 3, during the path confirmation stage, is used to convert the signal type and output an analog signal. Its input end is connected to the output end of the IO module connector docking unit 1, and its output end is connected to the system platform unit 7.

[0010] During the debugging phase, the signal oscillation generator unit 2 is used to receive debugging instructions from the electronic model of the control unit corresponding to the electronic model of the component under test in the system platform unit 7, and output simulated oscillation signals to the IO module connector docking unit 1 and the component under test.

[0011] System platform unit 7 includes design drawings, which are made according to the layout of various components on the electromechanical engineering site, and include electronic models corresponding to the components.

[0012] Preferably, system platform unit 7 includes:

[0013] Design storage unit 71 is used to pre-generate and store design drawings;

[0014] The response unit 72 is connected to the output terminal of the electronic model of the control unit in the design drawings. It is used to receive the feedback signal output by the electronic model of the control unit. If the signal transmission path is not interrupted, the response unit 72 will flash.

[0015] The collection unit 73 collects the debugging log information involved in the debugging process, and receives the debugging log information output by the electronic model of the control unit in the design drawings.

[0016] Preferably, it also includes a cable length measurement and calculation unit 6, which is integrated into the controller unit 8, for measuring the cable length between the pre-installation location and the controller unit 8.

[0017] Preferred, the field transceiver analog-to-digital circuit processing unit 5 is located at the field end where the component to be tested is installed.

[0018] Preferably, the IO module connector docking unit 1 is the front connector of the IO module.

[0019] Preferably, the system platform unit 7 is integrated into the controller unit 8 or located on the PC terminal 10.

[0020] Preferably, the component to be tested is an instrument or a valve.

[0021] A commissioning method for electromechanical engineering includes the following steps:

[0022] Step 1: System platform unit 7 generates design drawings;

[0023] Step 2: Estimate the pre-installation location and install the other units of the electromechanical engineering commissioning system;

[0024] Step 3: Start the oscillation generator. The oscillation signal passes sequentially through the field transceiver digital-to-analog circuit processing unit 5, IO module connector docking unit 1, digital-to-analog circuit processing unit 3, and signal oscillation generator unit 2, and is finally transmitted to the system platform unit 7.

[0025] If the electronic model corresponding to the component to be tested in the design drawings responds, the signal transmission path will not be interrupted, and the path confirmation stage will end.

[0026] Step 4: In system platform unit 7, for the electronic model corresponding to the component under test, the electronic model of the control unit issues debugging instructions and outputs simulated oscillation signals to IO module connector docking unit 1 and the component under test.

[0027] Step 5: Observe and record the output response of the component under test. If the error with the debugging command exceeds the preset range, proceed to step 1.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] (1) For various instruments, valves and other components to be tested, the debugging process only involves two observation positions with one observer at each position. All other processes are carried out automatically, which can realize automatic debugging.

[0030] (2) Debugging and drawing modification are carried out simultaneously: After the path confirmation stage is completed, the debugging stage is entered; in the system platform unit 7, for the electronic model corresponding to the component to be tested, the electronic model of the control unit issues debugging instructions and outputs signals to the IO module connector docking unit 1 and the component to be tested; observe and record the output response of the component to be tested. If the error with the debugging instructions exceeds the preset range, step 1 is executed. Step 1 is the process of generating design drawings by the system platform unit 7. Therefore, debugging and drawing modification are carried out simultaneously. Attached Figure Description

Detailed Implementation

[0035] The electromechanical engineering debugging system and debugging method of the present invention will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0036] like Figures 1-3 As shown, a debugging system for electromechanical engineering includes: an IO module connector docking unit 1, a signal oscillation generator unit 2, a digital-to-analog circuit processing unit 3, a system network unit 4, a field transceiver digital-to-analog circuit processing unit 5, a cable length measurement and calculation unit 6, a system platform unit 7, a controller unit 8, and an oscillation generator 9.

[0037] In this embodiment, the component to be detected is an instrument or a valve.

[0038] Specifically, the oscillation generator is used to generate oscillation signals, and during the path confirmation stage, it is set at the pre-installation position of the component to be tested.

[0039] The field transceiver analog-to-digital circuit processing unit 5, located at the field end where the component under test is installed, is used to receive the oscillation signal emitted by the oscillator and convert it into a signal type. Its output is connected in sequence to the IO module connector docking unit 1 and the control unit 8. The IO module connector docking unit 1 is the front connector of the IO module for the Siemens 300 series PLC.

[0040] The controller unit 8 includes a digital-to-analog circuit processing unit 3 and a signal oscillation generator unit 2.

[0041] The analog-to-digital circuit processing unit 3, during the path confirmation stage, is used to convert the signal type and output an analog signal. Its input terminal is connected to the output terminal of the IO module connector docking unit 1, and its output terminal is connected to the system platform unit 7.

[0042] During the debugging phase, the signal oscillation generator unit 2 receives debugging commands from the electronic model of the control unit corresponding to the electronic model of the component under test in the system platform unit 7, and outputs a simulated oscillation signal to the IO module connector docking unit 1 and the component under test.

[0043] System platform unit 7 includes design drawings, which are made according to the layout of various components on the electromechanical engineering site, and include electronic models corresponding to the components. The components in the design drawings include the electronic models of the aforementioned components to be tested and the electronic models corresponding to the control units.

[0044] The system platform unit 7 is integrated into the controller unit 8 or located on the PC 10, and includes: a design storage unit 71, a response unit 72, and a collection unit 73. When the system platform unit 7 is integrated into the controller unit 8, the PC 10 accesses the system platform unit 7 through the system network unit 4.

[0045] Design storage unit 71 is used to pre-generate and store design drawings.

[0046] The response unit 72 is connected to the output terminal of the electronic model of the control unit in the design drawings. It is used to receive the feedback signal output by the electronic model of the control unit (when the electronic model of the control unit successfully receives the signal from the digital-to-analog circuit processing unit 3, the electronic model of the control unit sends a feedback signal to the response unit 72). If the response unit 72 flashes, the signal transmission path is not interrupted. More specifically, the response unit 72 is an indicator light electronic model. After observing the response, the observer inputs a debugging command to the electronic model of the control unit to enter the subsequent automatic debugging stage.

[0047] The collection unit 73 collects the debugging log information involved in the debugging process, and receives the debugging log information output by the electronic model of the control unit in the design drawings.

[0048] When returning to step 2 in step 5, the control unit electronic model will generate a debugging log. During the debugging process, changes in the instrument positions or cable positions in system platform unit 7 will be recorded by the control unit electronic model in system platform unit 7. At the same time, field personnel can also send the actual positions of field instruments or confirm the correct field information by operating the field oscillation generator. The control unit electronic model in system platform unit 7 will collect this information for field debugging records.

[0049] The cable length measurement and calculation unit 6 is used to measure the cable length between the pre-installation location and the controller unit 8, and it is integrated into the controller unit 8. The principle of the cable length measurement and calculation unit 6 is based on the four-endpoint measurement technology, namely the Kelvin measurement method.

[0050] The commissioning methods for electromechanical engineering, based on the aforementioned commissioning system for electromechanical engineering, specifically include:

[0051] Step 1: System platform unit 7 generates design drawings.

[0052] Specifically, the software library integrates electronic models of mainstream PLC IO modules, relays, signal isolators, and other equipment, and users can also create their own. Each time a model is dragged and dropped into the editing screen, a record is created. The menu bar also displays cable diagrams, which are recorded each time they are used.

[0053] The overall design of the drawings is actually a drag-and-drop process. Once the initial design is completed, the drawings can be handed over to the engineers.

[0054] Step 2: Estimate the pre-installation location and install the other units of the electromechanical engineering commissioning system.

[0055] Step 3: Start the oscillation generator. The oscillation signal passes sequentially through the field transceiver digital-to-analog circuit processing unit 5, IO module connector docking unit 1, digital-to-analog circuit processing unit 3, and signal oscillation generator unit 2, and is finally transmitted to the system platform unit 7.

[0056] If the electronic model corresponding to the component to be tested in the design drawings responds, it indicates that the signal transmission path is uninterrupted and the path confirmation stage is over.

[0057] Otherwise, further check the connection of the signal path, and then repeat step 3 until the electronic model corresponding to the component to be tested in the design drawings responds, and then proceed to step 4.

[0058] Step 4: In system platform unit 7, for the electronic model corresponding to the component under test, the electronic model of the control unit issues debugging instructions and outputs signals to IO module connector docking unit 1 and the component under test.

[0059] Step 5: Observe and record the output response of the component under test. If the error with the debugging command exceeds the preset range, proceed to step 1. In this step, the operator observes the output response. When the component under test is an instrument, the output response is the swing amplitude; when the component under test is a valve, its output response is the opening and closing amplitude.

[0060] The above are merely preferred embodiments of the present invention and do not constitute any limitation on the present invention. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and content disclosed in the present invention without departing from the scope of the present invention shall be deemed to have remained within the protection scope of the present invention.
